tribute it at and in the direction ot' the crown or center of the road,thus building the roadN np in the most approved manner.

' It is a further purpose of the invention to provide means for insuringe. straight drclt and means for lifting the forward ends of the machineso that it may pass obstructions and readily cross bridges, enlverts andthe 'T he 'invention consists in a V- shaped frame ada ted to drag atits divergent ends or to be w eel-supported st such points, and to soconstruct the frame that steering -or vdirecting members will -beprovided at its converging .ends whereby to insure the device preservingn predetermined ath.

In the drawings that serve to illustrate my invention, I haveillustrated the preferred Aform of the device, but I desire it to beunderstood that the construction of the frame may be changed andlikewise the means for raising and lov-'ering the forward lprortion ofthe frame without departing om the spirit of the invention.

In'the drawings, Figure 1 is o len view of the drag; Fig. 2 is s sideelevation thereof;

Fig. `3 is alongitudinsl vertical section taken practically on the liney3-3 of Fig. 1, and lig. 4 is a transverse detail section tokenessentially on the line 4-4 of Fig. 1.v

Like characters of reference deslgnate corres ending parts in all theviews.

n the construction of the frame of the device, two divergent side piecesA and A are employed, that converge et their rear ends and diverge attheir forward ends. ihese side beams or pieces are connected at thefront by a cross ber l() and :it thc rear by e cross bar 11 secured inany sritsble mon'- ner to the bes-ms A and A,'and the construction ofthe frame is completed by the add ition of intermediate longitudinalbars 12 ond 13 that extend fro1n one cross bei' 10 to the other 1l andnrc made fast thermo, is particularly shown in Fig. 1.

Boxes 14; are carried by the side beams .fr and A aipljacent to theirforward ends, and in these boxes, crank nxles 15 are mounted. Wheels 16are loosely carried at the outer ends of the axles; and nt the innerends of each axle a lever 17 is secured, whereby to reise and lower theforward endof the device to elevate it when passing obstruct ions and tolower the frame to bring the critters or Scrapers into action when theobstrictions to operation have been passed. The wheels .in servicepromote the 'passage of the dcvif-e to and from the field ot' action,und can be held in ndjnsted position by thumb latches 19 in the levers17, that engage with rocks i on the side beams A and A.

Any known .means may be employed for sdjusting the throw of the axles 15to nislie the Scrapers out more or less deeply.

The draft chains 20, or their equivalents, are ntts'clied to the'forward' end portions of the side beams A end A', as nre the cutters orScrapers 21, shown. best in Fig. These cutters or sera-pers 21 arescoured to the lower inside. edges of the booms A end A" et their'forward portions, es shown in Fi s. 1 und 3, end extend from the frontends 0% the beams Aend A to s point ot or near their centers. Theseserav )ers consist of a longitudinal vertical mem er a. thatextends-irren onel endof it beam to the-other st its inner side, end ahorizontal cutting or scraping blade o that extends inwordct .rightsingles to the member ay an d which terminates et thc point nbovementioned.

The member al oi the critter or scraper beyond the binden, follows theinner, lower edge portion oi' o. side beam ond is sttoched thereto,which continuation is designated as 29 in the drawings and 'may becarried be-A neeth the lower edge ol' the benin to which it is applied.

The inner toc-cs 1.2 theresr ends ol' the side beams A ond A :treinclined its is sho-.vn in Fig. 1', and at such points guide teeth orblades 23 are secured, which muy., il desired,`

be portions of the protective strips lhese teeth or blades enteringtheground, serve to keep the device in operation in estrsight or directline, preventing the device from shifting laterally.

A. device olf the chz'trocter described is not only simple, but it willell'ectively and quickly scrape and crown a road bed, and can be safelyconducted over obstructions and quickly placed in operation when theobstructions are passed.

Having thus described my invention, I claim as new and desire 'to secureby Letters Patent:

' V1. In a road drag, a substantially triangular-shaped frame, andScrapers or cutting i blades at the forward portions of the frame,

. bers diverging at ltheir forward ends, and

Scrapers at the forward portions of the side members, the said Scrapersconsisting of longitudinal vertical members secured to the inner facesof said side members of the frame,

and horizontal cutting members extendinginward from the lower edges ofsaid vertical members and at right angles thereto.

3. In a road drag, a substantially triangular-shaped frame having sidepieces diverglng at their forward ends, and Scrapers comprisinghorizontal cutting members extending inward from the lower edge of saidside ,members at the forward portions thereof.

4. In a road drag, scraper blades at the forward end portions of thedrag at opposite sides thereof', the said blades each comprisinganinwardly extending horizontally arranged cutting member, and guidedevices adapted to enter the ground at the rear end portion of the drag.

5. In a road drag, the combination with a siens substantiallytriangular-shaped frame, the side pieces whereof are separated at theirrear converging ends and having their inner facesbeveled at said ends,of Scrapers consisting of longitudinal vertical' members secured to theinner faces of said side members of the frame and extending from thefront end of the side members to the rear thereof and horizontal cuttingor scraping members extending inward from the forward portion of saidvertical members and at right angles thereto, and guide blades at therear ends of said longitudinal vertical members of the scrapers andadapted to enter the ground, the said guide blades'being secured to thebeveled inner faces at the rear ends of said side pieces. v

. 6. In a road drag, the combination with a substantiallytriangular-shaped frame, the side pieces whereof are separatedl at theirrearconverging ends and having their inner faces beveled at said ends,of Scrapers se'- cured to the inner faces of theside pieces of the frameand consisting of longitudinal vertical strips extending from the frontend of the side members to the rear thereof and horizontal cuttingmembers, extending inward from the forward end ortion of said verticalmembers,A guide bla es at the rear ends of said longitudinal strips andsecured 'to the beveled inner faces at the rear ends of the side pieces,means for raising and lowering the forward portion of the frames, anddraftv means secured to the forward portion of the frame.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.
